Locking Component For An Embolic Filter Assembly

View page
US Patent:
7678129, Mar 16, 2010
Filed:
Mar 19, 2004
Appl. No.:
10/805455
Inventors:
Douglas H. Gesswein - Temecula CA, US
David K. Wrolstad - Temecula CA, US
David H. Burkett - Temecula CA, US
Robert C. Esselstein - Fallbrook CA, US
Kathern J. Lind - Temecula CA, US
Pablito Buan - Temecula CA, US
Robert C. Hazelden - Temecula CA, US

Assignee:
Advanced Cardiovascular Systems, Inc. - Santa Clara CA
International Classification:
A61M 290/00
US Classification:
606200, 600585
Abstract:
A locking component for locking a medical device onto a guide wire. Such medical devices include, for example, an embolic filter assembly used to capture embolic material that may be created and released into a patient's vasculature during a stenting or angioplasty procedure. The embolic filter assembly tracks along the guide wire, and is delivered to a treatment site where it is locked in place and deployed. The locking component enables the filter assembly to lock onto any standard guide wire, and does not require a modified guide wire that has a specially-designed fitting or stop to accomplish the locking function.

US Patent:
7959667, Jun 14, 2011
Filed:
Dec 21, 2006
Appl. No.:
11/643208
Inventors:
Diem Uyen Ta - San Jose CA, US
Caroline Wu - San Jose CA, US
Brenna K. Hearn - San Francisco CA, US
Daniel L. Cox - Palo Alto CA, US
Leonard D. Barbod - San Diego CA, US
Jessie Delgado - Murrieta CA, US

Thomas Ray Hatten - Los Altos CA, US
David K. Wrolstad - Temecula CA, US
Kenneth Kay Armstrong - Riverside CA, US
Darrin J. Kent - Murrieta CA, US
Assignee:
Abbott Cardiovascular Systems Inc. - Santa Clara CA
International Classification:
A61F 2/06
US Classification:
623 135
Abstract:
An improved stent design and stent delivery catheter assembly for repairing a main vessel and a side branch vessel forming a bifurcation. The stent includes rings aligned along a common longitudinal axis and connected by links, where the stent has one or more portals for aligning with and partially expanding into the opening to the side branch vessel. The stent is implanted at a bifurcation so that the main stent section is in the main vessel, and the portal section covers at least a portion of the opening to the side branch vessel. A second stent can be implanted in the side branch vessel and abut the expanded central section to provide full coverage of the bifurcated area in the main vessel and the side branch vessel. Radiopaque markers on the stent and on the tip of the delivery catheter assist in aligning the portal section with the opening to the side branch vessel.
